Camera Focal Length Adjustment
1. Select the camera in the ‘Scene’ tab.
2. Open the ‘Parameters’ tab if it is not already open.
3. Select the ‘Camera’ entry.
4. Adjust the ‘Focal Length’ slider or direct entry in mm for the focal length.
Note, you will of course have to reposition the camera to achieve the same framing of the shot for a different focal length.

To get the effect you want I think you need to set it to 35-45 or maybe less depending on your setup.
